The circumference of the circle below is 20 cm. What is the length of AB (the minor arc)?

SOVA2 [1]

Answer: $AB=5.27\ cm$

Step-by-step explanation:

For this exercise it is important to remember that, by definition, the length of the minor arc can be calculated wih the following formula:

$arc\ length=(\frac{central\ angle}{360\°})(circumference)$

In this case , according to the data given in the exercise, you know that:

$arc\ length=AB\\\\central\ angle=95\°\\\\circumference=20\ cm$

Therefore, susbtituting those values into the formula, you get that length of AB is the following:

$AB=(\frac{95\°}{360\°})(20\ cm)\\\\AB=(\frac{191}{72})(20\ cm)\\\\AB=5.27\ cm$

Math help? 15 points!

GenaCL600 [577]

The answer is
y = x/2 - 5! This is the same as
y = (1/2)x - 5 so don't be tricked by the way x is on top of 2
1/2 is the slope and -5 is the y int

The simple interest I on an investment of P dollars at an interest rate r for t years is given by I=Prt. Find the time it would

Darina [25.2K]

we know that

$I=Prt$

where

I is the amount in interest

P is the investment

r is the interest rate

t is the time in years

Solve for t

$t=I/(Pr)$

we have

$I=\$1,400\\ P=\$27,000\\ r=4.2\%=0.042$

substitute

$t=1,400/(27,000*0.042)=1.23\ years$

therefore

<u>the answer is</u>

$1.23\ years$
